Porosity is the key factor in determining the CO₂ capture capacity for porous carbon-based adsorbents, especially narrow micropores of less than 1.0 nm. Unfortunately, this desired feature is still a great challenge to tailor micropores by an effective, low-corrosion, and environmentally friendly activating agent. Herein, we reported a suitable dynamic porogen of CuCl₂ to engineer microporous carbons rich in narrow micropores of <1.0 nm for solving the above problem. The porosity can be easily tuned by varying the concentration of the CuCl₂ porogen. The resultant porous carbons exhibited a multiscale micropore size, high micropore volume, and suitable surface nitrogen doping content, especially high-proportioned ultromicropores of <0.7 nm. As adsorbents for capturing CO₂, the obtained microporous carbons possess satisfactory CO₂ uptake, moderate heat of CO₂ adsorption, reasonable CO₂/N₂ selectivity, and easy regeneration. Our work proposes an alternative way to design porous carbon-based adsorbents for efficiently capturing CO₂ from the postcombustion flue gases. More importantly, this work opens up an almost-zero cost and industrially friendly route to convert biowaste into high-added-value adsorbents for CO₂ capture in an industrial practical application.

The aim of this study was to investigate the effects of Idesia polycarpa fruit blackening on fruit and seed morphological characteristics, oil content, fatty acid content, seed germination rate and physiological properties. Germination tests were conducted under dry and wet storage at 5 °C for 0 d, 20 d, 40 d, 60 d and 80 d. The fruit mass, the 100-grain weight, the moisture content, the oil content of seeds and oleic acid in unsaturated fatty acids of black fruit are significantly lower than red fruit (P < 0.05). The germination rate of black fruit seeds was higher than red under wet storage and the malondialdehyde content of black fruits decreased with increasing storage time. Our results demonstrated that black fruits of I. polycarpa should not be discarded indiscriminately and that the color of the fruits can be chosen according to the purpose of use. Black fruits are picked for species propagation, while red fruits are mainly harvested for oil extraction.
